Caiman (genus)

Caiman is a genus of reptile in the Alligatoridae family. They are found in Central and South America, and differ from the alligator by the absence of a bony septum between the nostrils, and the ventral armour is composed of overlapping bony scutes, each of which is formed of two parts united by a suture. Caimans tend to be more agile and crocodile-like in their movements, and have longer, sharper teeth than alligators. Although the Caiman has not been studied in-depth, scientists have learned that their mating cycles (previously thought to be spontaneous or year-round) are linked to the rainfall cycles and the river levels, which increases chances of survival for their offspring.
